-- The Improved Inter-Integrated Circuit (I3C) is a simple and cost-efficient bidirectional 2-wire synchronous serial bus protocol developed by the Mobile Industry Processor Interface (MIPI) Alliance.
-- I3C is backward compatible with legacy Inter-Integrated Circuit (I2C) devices. Moreover, it provides the in-band interrupt (IBI) function and supports hot-join of I3C devices. This eliminates the need for adding an extra interrupt line to implement interrupts in I2C.
-- The I2C device, I3C slave device, and I3C secondary master device can coexist on the I3C bus.
--   The I3C APIs provide a set of common functions for I3C transfer, including:
